Quora

The other day I mentioned a site called quora.com that crowd-sources questions of all sorts.  I joined up and have been enjoying the occasional email alerting me to new posts.  Here's a link to a collection of suggestions for handy tips.  I can't quite make out whether you'll be able to access it without joining the site, but if not, I recommend joining.  The article is entitled "What’s something a reasonably smart person likely doesn't know but would find incredibly useful?" The first answer is a list of Google search tools. A couple of items down is a short video showing how to separate an egg yolk from the white by slurping it up with a squeezed-and-released plastic soda bottle.  Later on there are instructions for creating an amplifier for your smartphone/music player out of a toilet-paper roll and a couple of push-pins.  Or you can recharge your computer in a hotel room by plugging it into the USB port on the room's TV set.
